Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If conventional cellular networks increase complexity to expand capabilities, then network functionality is improved, but validation and management becomes tremendously challenging

Engineering Contradiction:

Improvenetwork capabilityVSAvoidnetwork complexity

Core Design Contradiction:

Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The patent uses virtualization to create virtual copies of network functions (VNFs) that run on standardized cloud infrastructure. Instead of managing complex physical network equipment, the system copies network functionality into software instances that can be deployed, scaled, and managed through virtualization orchestration, thereby expanding capabilities while simplifying validation and management through standardized virtual interfaces

Inventive Principle:

Principle #26Copying

Solution Approach 2:

The patent implements a universal cloud-based platform that can host multiple network functions and serve different cellular network requirements through a common infrastructure. The virtualized network functions can be dynamically allocated and configured to provide diverse capabilities (5G core, edge computing, network slicing) on the same physical infrastructure, improving adaptability while maintaining manageable complexity through standardized operations

Inventive Principle:

Principle #6Universality (Multi-functionality)

2Adaptability or versatility

If conventional cellular networks increase complexity to expand capabilities, then network functionality is improved, but flexibility and reliability deteriorate

Engineering Contradiction:

Improvenetwork capabilityVSAvoidnetwork reliability

Core Design Contradiction:

Adaptability or versatilityVSReliability

Solution Approach 1:

The patent segments network functions into independent virtualized instances that can be deployed, managed, and failed over independently. By dividing the network core into separate VNFs (session management, mobility management, user plane functions), the system achieves both expanded capability through modular additions and improved reliability through isolated failure domains where one segment's failure doesn't compromise the entire network

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The patent enables dynamic parameter changes in network configuration through software-defined networking. Network parameters such as bandwidth allocation, routing policies, and service configurations can be modified in real-time without physical reconfiguration, allowing the network to adapt to changing requirements while maintaining reliability through controlled parameter transitions and validation

Inventive Principle:

Principle #35Parameter changes

3Adaptability or versatility

If conventional cellular networks increase complexity to expand capabilities, then network functionality is improved, but ease of operation deteriorates

Engineering Contradiction:

Improvenetwork capabilityVSAvoidnetwork management

Core Design Contradiction:

Adaptability or versatilityVSEase of operation

Solution Approach 1:

The patent introduces cloud-based orchestration platforms and management interfaces as intermediaries between network operators and the complex virtualized infrastructure. These intermediary systems provide standardized APIs, automated provisioning, and centralized control planes that simplify operations by abstracting the underlying complexity of virtualized network functions, allowing operators to manage expanded capabilities through user-friendly interfaces rather than direct infrastructure manipulation

Inventive Principle:

Principle #24Intermediary (Mediator)

AI summary

Systems, methods, and machine-readable media facilitate a cellular network. A cellular network infrastructure may be overlaid on a cloud environment so that a virtual cellular network core is integrated in a cloud environment to run a 5G core and provide 5G services. The virtual cellular network core may include a plurality of virtual routers operated as virtual machines and configured to provide functions of the 5G core. Each virtual router of the plurality of virtual routers may be communicatively connected with one or more other virtual routers of the plurality of virtual routers through an underlay infrastructure corresponding to the cloud environment. One or more component failures in the cellular network infrastructure that overlays the cloud environment may be caused. One or more operations of the virtual cellular network core may be determined consequent to the one or more component failures.
